Delta method for glm

Antonio_Paredes
Hello everyone.

I am trying to get a confidence interval for the risk ratio
(vaccinates/control) from the following model:

fit.1<-glm(sick~trt + loc, data=b, family=binomial).

here trt is one for vaccinates and 0 for control, loc is a binary (1/0)
variable.

I am trying to get a reference to apply the delta method to get my CI. Any
ideal?
